Polyethylenimine (PEI)i polymer inonyungudika nemvura. Iko kusungirirwa mumvura yezvigadzirwa zvekutengesa kunowanzo 20% kusvika 50%. PEI inoitwa polymerized kubva ethylene imide monomer. Iyo inonzi cationic polymer inowanzoita semvura isina ruvara kusvika kune yero kana yakasimba ine uremu hwakasiyana-siyana uye maumbirwo akasiyana.

Chiipolyethyleneiminebasa?

1. High adhesion, high absorption amino group inogona kuita ne hydroxyl group kuti iite hydrogen bond, amine group inogona kuita ne carboxyl group kuti iite ionic bond, boka reamine rinogonawo kuita nekabhoni acyl boka kuti riumbe covalent bond. Panguva imwecheteyo, nekuda kweboka rayo repolar (amine) uye hydrophobic boka (vinyl) chimiro, inogona kusanganiswa nezvinhu zvakasiyana. Nemasimba aya akazara anosunga, anogona kushandiswa zvakanyanya muminda yekuisa chisimbiso, inki, pendi, binder uye zvichingodaro.

2. High-cationic polyvinyl imide iripo muchimiro chepolycation mumvura, iyo inogona kuderedza uye adsorb zvose anionic zvinhu. Inoitawo chelates heavy metal ions. Iine yakakwirira cationic zvimiro, inogona kushandiswa mukugadzira mapepa, kurapwa kwemvura, plating mhinduro, dispersant uye mamwe minda.

3. Yakanyanya kushandiswa polyethylenimine nekuda kweakanyanya reactive primary and secondary amines, saka inogona kuita nyore nyore ne epoxy, acids, isocyanate compounds uye acid magasi. Uchishandisa pfuma iyi, inogona kushandiswa se epoxy reactant, aldehyde adsorbent uye mumiriri wekugadzirisa ruvara.

Chii chinonzi polyethylenimine chinoshandiswa?

Polyethylenimine (PEI)musanganiswa wepolymer musanganiswa une akasiyana mashandisiro, kusanganisira asi asina kugumira kune:

1. Kurapa kwemvura uye indasitiri yemapepa. Semumiriri wesimba rakanyorova, rinoshandiswa mumurimmed inonwisa bepa (senge bepa rekusefa, inki yekudzima bepa, pepa rechimbuzi, nezvimwewo), iyo inogona kuvandudza kunyorova kwebepa uye kuderedza kukuvadzwa kwekugadziriswa kwepepa, uku ichimhanyisa kusefa kwemvura yepulp uye kugadzira mafibhi akanaka nyore kuyerera.

2. Mucherechedzo wekugadzirisa mavara. Iine simba rakasimba rekusunga madhayi ane acid uye inogona kushandiswa semugadziri wekugadzirisa apo acid inodhaya bepa.

3. Fiber kuchinjwa uye dhayi ebetsero. Kurapwa kwefiber, senge nhumbi dzokurwa, anti-kucheka magurovhosi, tambo, nezvimwe.

4. Zvigadzirwa zvemagetsi. Mumunda wemagetsi, polyethylene imide firimu inogona kushandiswa seyakagadzika dhizaini, insulating zvinhu uye inovhara layer yezvigadzirwa zvemagetsi, nezvimwewo, nekuita kwakanaka kwekudzivirira uye kupisa kwakanyanya.

5. Kuputirwa kwezvokudya. Sechikafu chekurongedza zvinhu, ine zvakanakira hunyoro-humbowo, yakanaka gasi kuramba, isiri-chepfu, isina kuravira, yakanyanya kupisa tembiricha, nezvimwewo, uye inoshandiswa zvakanyanya mukurongedza nyama, huku, michero, miriwo, kofi uye zvimwe zvigadzirwa.

6. Zvishandiso zvekurapa. Polyvinylimine inogona kushandiswa mumidziyo yekurapa, maturusi ekuongorora, kurongedza kwezvokurapa, nezvimwe, senge mapfekero ekurapa uye mafirimu akajeka ekurapa.

7. Adhesive. Sekunamira kwepamusoro-soro, inoshandiswa mukugadzirwa kweaerospace, zvigadzirwa zvemagetsi, zvikamu zvemotokari uye zvichingodaro.

8. Mvura yekuchenesa mvura uye inoparadzira. Inoshandiswa zvakanyanya mukugadzira mapepa emvura kurapwa, electroplating mhinduro, dispersant uye mamwe minda. Gene mutakuri. Polyvinylimide isiri-vhairasi vheti yekuunza majini, kunyanya yakakodzera kubatanidzwa-kutapurirana kweakawanda maplasmids.

Pamusoro pe,polyethyleniminezvakare ine hunhu hwekunamatira kwakakwirira, kukwirisa adsorption, yakakwirira cation, yakakwirira reactivity, nezvimwewo, uye inoshandiswa zvakanyanya muminda yependi, inki, adhesive, fiber kurapwa, sewage treatment nezvimwe zvakadaro.

Kazhinji, polyvinylimide imhando yepolymer ine huwandu hwakawanda hwekushandisa, uye zvimiro zvayo zvinogona kugadziridzwa uye kugadziridzwa nekuchinja mamorekuru huremu, chimiro uye kushanda.
